  5. Flash storage advantage • Flash Memory: • solid state • small size • non volatile • low power • reliable • Flash Cards: • mobile • small form factor • standardized • interoperable • shock & temperature endurance • easy to use

  6. Flash storage disadvantage • Flash Memory: • price / MByte • data retention • data transfer rate • limited erase cycles • access restrictions • Flash Cards: • „low“ capacity • 7 different formats

  7. Different Flash Technologies Flash storage advantage Several types of Flash Cards Flash Card applications Conclusion Contents:

  8. Types of Flash Cards: • Linear Flash • PCMCIA, 1989 • credit card size • 68 Pin, Memory-I/O • linear, ATA interface • Type I, II, III • NOR Flash , XIP • no build-in controller • Compact Flash • CFA, 1994 • matchbook size • 50 Pin, Memory-I/O • ATA, IDE interface • Type I, II • NAND Flash • build-in controller

  9. Multimedia Card • MMCA, 1997 • post stamp size • 7 Pin, serial interface, SPI • block/ streaming mode • NAND Flash • build-in controller Types of Flash Cards: • Smart Media • SSFDC, 1996 • thinnest form factor • 22 Pin, multiplexed I/O • single/ sequential blocks • pure NAND Chips • no build-in controller

  10. Memory Stick • Sony proprietary, 1998 • chewing gum size • 10 Pin, serial interface • security (magic gate) • NAND Flash • build-in controller Types of Flash Cards: • SD Card • SDA, 2001 • MMC compatible (thicker) • 9 Pin, serial/parallel interface • security feature, Memory-I/O • NAND Flash • build-in controller

  11. Types of Flash Cards: • xD Card • Olympus, Fuji, proprietary, 2002 • smallest card format (penny size) • 18 Pin, multiplexed I/O • NAND Flash • no build-in controller
